Patent GB-418403-A (GB)
Title: Improvements in or relating to the electrical precipitation of suspended particles from gaseous fluids
IPC: B03C3/66
Filed: 1933-09-20
Abstract: In an electrical precipitation system comprising a number of treater units connected in parallel to a single source of high tension current, spurious oscillations and surges are minimized by connecting surge-resisting impedances in each of the supply lines to the individual discharge electrodes and also connecting surge-resisting means may comprise a single from the collecting electrodes.  The latter surge-resisting means may comprise a single impedance in the common return lead or individual impedances in each lead to a collecting electrode or a combination of both.  Suitable impedances include chokes, resistances, thermionic valves or combinations thereof.  Fig. 2 shows a typical arrangement in which resistances A are interposed in the parallel leads to each discharge and collecting electrode. Fig. 6 shows an arrangement in which four thermionic valves K are used as rectifiers for each precipitation unit and resistances R are interposed in each lead between the transformer and the point of rectification.  The resistances in series with each unit are preferably 100,000 ohms or more, and may be wire-wound, carborundum rods or semi-conducting materials <PICT:0418403/III/1> <PICT:0418403/III/2> <PICT:0418403/III/3> <PICT:0418403/III/4> <PICT:0418403/III/5> <PICT:0418403/III/6> such as Portland cement concrete.  The use of semi-conducting materials of this type enables the resistances to be inserted close to the supports of the discharge and collecting electrodes or to be incorporated with the dischargeelectrodes.  Fig. 10 shows an arrangement in which the discharge electrodes are suspended from metallic pipes F and connection to a steel beam D carrying the high tension current is made through a block O of high resistance or semi-conducting material.  Alternatively the single block O may be dispensed with and individual blocks of such material inserted in each discharge electrode wire.  The discharge electrode may also consist of a flat block of semi-conducting material having a central conductor and definite wire discharge points are inserted along the edges.  Two examples are shown in Figs. 14 and 14<a> and 15, the former consisting of a block of such material suspended by a metal chain 16 and having discharge points 15, and the latter comprising hollow blocks 11 with arms 12, arranged on a central conductor 10, the arms 12 having discharge points 13.  In these cases, the discharge electrodes are preferably arranged with their longer dimension parallel to the flow of gas.

Abstract: 893,624. Transistor bi-stable circuits. LICENTIA PATENT - VERWALTUNGS - G.m.b.H. July 27, 1960 [Aug. 4, 1959], No. 26128/60. Class 40(6). [Also in Group XIX] A shift register 10, used for the serial conversion of parallel outputs of a decoder 11, comprises a series of stores S o  to S 3  which each receive an output of the decoder and which are rendered effective to store the output only on reception of a control pulse (t 2 ), the outputs of the stores S providing inputs to stores ZS u  to ZS 2  of similar construction and controlled by a pulse t 3  following t 2  the output of each store ZS except the last being an input to the store S next higher in the series. Each store S or ZS is preferably constructed as in Fig. 2, NPN transistors II and IV forming a flip-flop the state of which is exhibited by the potential at the terminal B. If a control pulse is not present at terminal t (0 volts), transistor I is not conductive, diode DI/III is conductive, as is transistor III, and diode DIII/IV is blocked, with the result that the flip-flop II/IV is unaffected by input pulses at e or z. A control pulse at terminal t (12 volts) sends transistors I and II conductive, breaking the feedback between transistors II and IV and blocking diodes DII/IV and DI/III. The condition of transistor III, and thus transistor IV, is dependent on the input signal at e or z. Because of the double phasereversal at transistors III and IV the output signal is in phase with the input.

Abstract: 723,712. Driving-gear for printing-machines. HALLEY & SONS, Ltd., J., and HALLEY, A. M. Oct. 26, 1953 [Oct. 21, 1952], No. 26358/52. Class 100 (2). In a printing-machine the cylinder driving mechanism allows ready adaptation for printing cylinders of different sizes and comprises a driven shaft 6 carrying bevel gears 7a, 7b meshing with gears 8a, 8b driving respectively the impression and printing cylinders. Connected to gear 8b is a gear 9, meshing with an equal gear 10 coupled to the printing cylinder 3. The gear 8a is connected by a shaft 11 to a pinion 12 connected through a movable gear 13 with a gear 14 driving the impression cylinder 1. Inking rollers 4, 5 co-operate with the printing cylinder 3, roller 5 being driven from a gear 15 on the other end of the impression cylinder connected through gears 16, 17 and 18. According to the invention the pinion 12 is interchangeable and is selected so that its diameter is always related in the same proportion to the diameter of the changeable printing cylinder. The gear 13 can be displaced to accommodate the pinions 12 of different size and the bearings of the impression cylinder are adjustable so that it may be positioned to accommodate different sizes of printing cylinder. Gear 16 driving the inking rollers is displaceable with the impression cylinder on arms pivoted on the axle of gear 17. The inking rollers are thereby driven at a speed depending on the speed of the impression cylinder. By this means the peripheral speeds of the impression cylinder and inking rollers are kept the same as the peripheral speed of the printing cylinders for the different sizes of the latter. Several printing couples may be embodied together in a multi-colour machine, the printing cylinders being driven by a series of bevel gears such as 7b spaced along shaft 6 and all the impression cylinders being driven through a single interchangeable pinion 12. Perforating mechanism may also be driven through this gear but cutting mechanism, where this is provided, is driven from shaft 6 so as to rotate at the same speed as the printing cylinder.

Abstract: 641,885. Endless-belt conveyers. MILIK CONVEYORS, Ltd. Sept. 3, 1946, No. 26459. [Class 78 (i)] Apparatus for coal conveying includes a single endless conveyer belt which has two disaligned portions a<1>, a<2> (Fig. 2) with a double loop f at the junction thereof, which junction advances progressively along the belt so that portion a<2> increases as portion a<1> decreases; and a framework F in which is rotatably mounted a set of sectional rollers, each consisting of a plurality of closely-set, laterally-adjacent and independently revoluble discs which combine to form for the roller a bulging contour corresponding to the cavity of the portion of the belt supported thereby, and form the advancing junction. Fig. 2. A single conveyer belt a, b, c, d passes along working roads A, B and along gate roads C, D. The belt is formed with a double-loop angle station f so that coal from loader-cutter E is fed on to belt a<2> and deposited into gate road D and goaf-filling material is fed from gate road C on the belt a<1> and swept by a plough forming part of the angle station so as to be deposited at this same spot at the coal-face. The angle station (and plough) moves with the loader-cutter as the latter works from right to left. When the latter reaches the end of the coal-face A the second loader-cutter E<1> and second angle station f<1> work similarly along coal-face B. The two loader-cutters therefore work alternately and the conveyer belt is moved bodily step-by-step in the direction of the retreating coal-face. Fig. 1. The belt is formed with portions a, b, c and d, there being triple-loop angle station f arranged so as to disalign the portions a and d. The portion a feeds away cut coal to the left; portion b feeds in goaf from the left, the goaf being swept off by plough P; and angle station f (and triple loop) moves steadily to the right (see dotted lines) following the coal-cutter. Fig. 3. The belt has two disaligned upper portions x, y, each of which has its corresponding lower return run immediately beneath it, and the two portions of the conveyer are brought out of alignment by the use of a twin double-loop angle station f. Coal is fed away from L on the upper run y to station D and goaf is fed in to D on upper run x from station L<1>. Specifications 599,130, 599,182, 599,185 and 644,293 are referred to.
